Termination arrangement for an overhead electrical cable
A termination arrangement for securing an overhead electrical cable to a dead-end structure such as a dead-end tower. The termination arrangement includes a compression sheath that is configured to be disposed between a strength member and the conductive strands of the overhead electrical cable. The compression sheath mitigates damage to the strength member that may occur when an outer metallic sleeve is compressed around the conductive strands and the conductive strands are compressed against the strength member. The arrangement is particularly useful for securing overhead electrical cables having a composite strength member to a dead-end structure.
Locking grounding clamp
A grounding clamp includes a safety lock-out which locks the operation of the clamp in the absence of a cooperating hot-stick. The lock-out employs a clutch which prevents the translation of the clamping members relative to one another until the clutch is disengaged. The cooperating hot-stick is required for the disengagement of the clutch.

Spring loaded ground clamp
A grounding clamp uses a spring driving a piston mounted movable jaw as a safety lockout. The movable jaw and a fixed jaw, which may include teeth, form a conductor clamp. The ground clamp mounts on the end of a hot stick to provide for electrically insulated remote operation of the ground clamp by a lineman holding the hot stick and pulling on, or releasing, a lever arm on the hot stick. The system provides increased safety for the lineman as the spring providing the spring loading of the clamp has a high spring force to overcome, thus providing the lockout. The lever arm on the hot stick tool provides mechanical advantage to overcome the spring force and thus release the lockout. The lineman cannot usefully operate the ground clamp manually without the hot stick due to spring force lockout.

ADJUSTABLE INSULATING DEVICE
An adjustable insulating device is provided. An example device includes a housing and an extendable member at least partially located within the housing. The extendable member moves between a retracted position and an extended position. The device further includes an adjustment mechanism operably coupled with the extendable member. The adjustment mechanism causes translation of the extendable member between the retracted position and the extended position. The adjustment mechanism includes a first roller rotationally engaged with the extendable member at a first position that houses a first motor, and a second roller rotationally engaged with the extendable member at a second position that houses a second motor. An output of the first motor and an output of the second motor are configured to cause translation of the extendable member between the retracted position and the extended position, via the first roller and the second roller.
